いる。2. Description of the Related Art A conventional damper pulley is, for example, as shown in FIG. 5, in which a central cylindrical boss portion 1 and a disc-shaped main body portion 2 extending outward from the central boss portion 1 are integrally cast to form a main body portion. The rubber elastic body 4 having a constant thickness is joined to the outer circumference of the inner circumference of the ring 2, and the outer circumference of the rubber elastic body 4 is joined to the inner circumference of the ring-shaped belt suspension portion 3 of the casting for suspending the belt 5. Then, the rotational driving force from the rotary shaft on which the boss portion 1 is mounted is transmitted to the belt 5 from the belt suspension portion 3 via the rubber elastic body 4. When torsional vibration occurs in the rotating shaft, the belt suspension portion 3 on the rubber elastic body 4 resonates and suppresses vibration of the rotating shaft. Since such a conventional damper pulley is a relatively thick cast product, it is heavy, and the vulcanization joining of the rubber elastic body 4 requires time and effort for applying an adhesive agent and the like, and the manufacturing cost is high. In this case, if the application of the adhesive is omitted, the rubber elastic body 4 slips in the rotation direction, and there is a possibility that the rotational force will not be transmitted at the extreme. Therefore, for example, in Japanese Utility Model Laid-Open No. Sho 63-37841, grooves are formed by serration processing on the outer peripheral surface of the pulley main body and the inner peripheral surface of the belt suspension section, each of which is provided with a rubber elastic body. , A part of the rubber elastic body press-fitted is filled to prevent the rubber elastic body from slipping.

The present invention solves such a problem, and an object of the present invention is to provide a damper pulley which is lightweight, can be manufactured easily and at low cost, and can prevent slipping of a rubber elastic body.

Power acts. Here, since the ridges 22 and 31 provided at a plurality of positions in the circumferential direction bite into the rubber elastic body 4 alternately from the inside and the outside to exert strong pressure, slip movement is effectively prevented. Thus, the rotational driving force is efficiently transmitted to the belt suspended by the belt suspension portion 3 via the rubber elastic body 4. Since the whole is compressed and deformed and the ridges 22 and 31 bite in, the rubber elastic body 4 is effectively prevented from coming off in the axial direction. If slipping or slipping out of the rubber elastic body 4 can be sufficiently prevented, it is not necessary to compress and deform the entire rubber elastic body 4.
